Wait I'm a little confused... how do you purchase a phone with an upgrade.. and then purchase another phone with an upgrade?
I assume that you paid $369 + tax for the phone... then sold it for $1000... and are trying to purchase it again for the $369 + tax? I don't know how that's possible since you already extended your contract for 1 year so you wouldn't be eligible for the 1 year pricing. If that was true... then everyone would be doing it to make money if they could get another phone for $369 to sell on Ebay.
So... -$369 + $1000 - $369 = $262 end if you were able to get another phone at $369
If you have to pay MSRP for ANOTHER phone... -$369 + $1000 - $569 = $69 net (excluding all taxes and the Ebay + Paypal fees)
Can you clarify how you were able to get the $700 figure? I think the 2nd one is the route that you have to take. You've already extended your contract 1 year with Verizon, so you're not eligible for another 1 year pricing. I'm assuming you have to pay full MSRP because Verizon is not going to allow you to get ANOTHER discounted phone with no strings attached.
